Console performance question

[MEC-777]

Well, the PS4 modded APU=7850 which =260x?

 

The APU in both consoles are custom designed using existing AMD CPU and GPU cores. The CPU chip in both consoles uses 8 AMD "Jaguar" mobile processor cores (basically two quad-core Athlon 5150's combined). The GPU chip for the XboxOne is based on the HD 7790 GPU core, while the GPU chip in the PS4 is based on the 7870 core. The clocks have been altered (from the desktop dGPU variants) and the PS4 uses GDDR5 memory, where as the XboxOne uses slower DDR3 memory. 

 

So they aren't "modded" APU's. They're basically custom made APU's combining mobile CPU processor cores with dGPU cores.

 

Another thing to note is the CPU of the XboxOne has an additional 32MB "cache" of eDRAM and is clocked slightly higher than that of the PS4.

Even PS4 gpu is based on a cut HD7870 chip, it should not be compared with 270 or 270x. It has less shaders, TMU's, CU's and it runs at quite lower frequencies, so the performance is nowhere near. Nowadays I find r7 370 (Overclocked HD7850) the best candidate to compare the performance of the ps4.

Actually the 7850= 265 not the 260x.

To be honest the GPUs in the consoles aren't that bad, they are actually ok when you factor in the API optimizations.

Its the shitty cpus that are causing most of the issues. Todays games are using far more cpu power.

Yep. IPC is very important. While the consoles do have 8-core CPUs, they are 8 VERY weak (low IPC) cores.

 

 

 

(For those that don't know, IPC = Instructions per cycle.)

Turn the quality of graphics down to low.

Put your PC to 720p Full screen. (The PS4 is only upscaling the video signal, not actually pushing out 1080)

From what I understand, the closest comparison is XboxOne GPU = 7790 (260X) and PS4 GPU = 7870 (270X). But it's important to note that they have both been down-clocked a little, so they're slightly handicapped versions. Also, the XboxOne is using DDR3 memory which further hampers performance a bit.

 

 

Im impressed that they can manage those visuals at those frames.

Witcher 3 (and other titles) are showing their age already though....I wish it was not the case...

 

"Ethan Carter" UE3<UE4 port on PS4, stutters like a bitch and runs at 30-45fps outside and 60fps indoors, moving from inside to outside, a sweeping 20-30fps drops in an instant.....super noticeable + input lag as well, non-synced, and you can see SEVERE stuttering, enough to change my mind buying it, but thats early days on that game, room for improvement I hope, but not if the Witcher3 shows that you can't polish a turd.... what hope do other demanding scenes have.

 

PS4 isn't playing at ultra settings. Console games don't have graphics settings, they're fixed at whatever level is low enough to get 30-45fps. Usually somewhere around the equivalent of low or medium on PC, but it depends on the game.

Also the PS4's GPU is about as powerful as a 270X.

In addition, the consoles use APIs with less software overhead than DX11, something similar to Mantle, so they can make more efficient use of their hardware.

This....

Plus....

Our very own early days PC exclusive...... Minesweeper.

 

/And the rest of the multipurpose software/apps/games/media/streaming you can use, you have the ability to run all of those at your own pleasure, even at the same time side by side... A $200 difference for ALL THAT FUNCTIONALITY

Worth every penny.

HAHAHAHAHAHAHAHAHAHAHAHAH 1080P ULTRA ON CONSOLES LOOOOOOOOOOOOOOOOL

 

Seriously though, they play at 720p (usually) and always on medium settings
